CHANNEL OVEN FOR CERAMIC AND` CHEMICAL PRPOSES.

Application filed June 27, 1925. Serial No. 40,012.

and to letters or figures ot reference marked thereon, which form a part of this specilication. v

This invention relates to a channel oven for ceramic and chemical purposes in which the combustion air and the gas prior to entering into the baking chamber, are mixed .v in spaces in the oven wall, the gas and air mixture being admitted into the baking chamber not only at one point, but at' several points situated at different heights.

The invention is characterized in that a greater numberv of mixing Vspaces for the i' gas and air mixture, said spaces comprising gas burners, are arranged above one another and the one at the side of the other in the oven wall, the gas burners being combined in several groups which are operated singly or several at the same time. Each burner group has one gas channel adapted to be regulated, while for the admission of the combustion air to the mixing spaces channels are provided which feed the air to the burner groups series-wise.

In the form of construction, illustrated in the accompanying drawings, every three mixing spaces in the oven wall are arranged to form tour burner groups, every two groups being superposed and each group being supplied with gas :trom the generator by a gas channel arranged laterallyof the burner groups. Owing to this arrangement the gas supplymay be increased or reduced at will in accordance with the temperature to be obtained, or forincreasingthe efficiency el'l the oven or to supply to the baking chambers for the several burner groups more or less heat at the upper or lower portioirof the same.

The arrangement is shown, by way of ex-l ample, in the 'accompanying drawings in which Fig. l is a longitudinal section through the oven.

Fig. 2 is a horizontalsection on line Ai-Bi `on the platform lot the carriage l. running on rails 2. The carriageadvances in the direction of the arrow 3. The-left side part of the channel oven, Fig. 1, serves as baking zone, the right side part as cooling Zone. The two gas supply channels 12, which come from a generator not shown in the drawing, ascend laterally of the burner groups I to IV and have horizontal branches 4, 4 extending underneath the mixing spaces 8. The gas supply is regulated by liaps 10. The burner groups I ,and II are supplied rwith gas from the left channel 12 and the burner groups III and IV from the right channel 12.

Pipes 6 in the cooling Zone lserve for supplying combustion air tothe mixing spaces 8 with the aid oli' the channels 7 arranged in the masonry. These channels 7 are situated above the mixing spaces 8 with which they communicate by a port. and they are adapted to be shut oit" by registers 9.y One air supply channel 7 is provided for each row or group of burners. Peepholes `11 are arranged for the observation of the mixing spaces 8.

Claims: a

1. A channel oven `for burning ceramic vand chemical deviceshaving a plurality of mixing chambers formed 4within the walls ot the oven and terminating in burners for air and gas mixture, supply channels for air, and separate supply Lchannels for gas communicating with the mixing chambers, and separate regulating means for the air and for the gas at each mixing chamber.

2. Channel oven for ceramic and chemical purposes,A comprising several mixing spaces, arranged above and at the side of one another and having air burners for thegas and air mixture, and supply channels for, gas and air opening yinto said mixing lspaces and adaptedto be regulated,`-sad supply channels having regulating elements at the points Where they communicate with said mixing spaces, said gus burners heing arranged to forin several burner groups.

3, Channel oven for ceramic und chemical purposes in which the several gas burners adapted to(be'reguluteclare arranged in roWs at the side of one another and theone above the other end in which the supply channels for supplying' gas and air to,V the horizontal burner rows extend horizontally.l euch single gas channel supplying one group of burners juxtaposed in a horizontal plane. In testimonyv that I olziini the.' foregoing ss my invention, I havev signed my nanie.
